The 8 inch HotChip flashers are fish catching leaders in the different types of flashers.  They are probably used in more applications that any other flasher series.  They are a trolling device that attract salmon with vibration from their kicking and spinning action. They are attached to your fishing line and then a bait, lure or hoochie is tied between 24 to 48 inches behind the flasher.  This tail leader length is the most important rigging feature in catching salmon,  See flasher rigging techniques at www.protroll.com The flasher can be dropped to depth using a downrigger, a diver or a lead weight.  Typical trolling speeds are 2.0 to 3.0 MPH    
The Glow Chartreuse Pro-Troll Hotchip flasher is another top producer.  Every year it is on the top ten sellers list because it catches lots of salmon. The brilliant Chartreuse  blade combined with the white glow tape on top and the embossed silver on the bottom is deadly.  This flasher should be in everyone's tackle box.  It will frequently produce when other flashers will not.
